Binary marble adding machine

[dock98]

Way back when I built my Marble Machine one , I incorporated a few logic-like elements in it, including several divide by two mechanisms, as well as a complicated and slightly unreliable divide by 6 mechanism.

It had occurred to me that perhaps with an insane amount of perseverance, it might be possible to build a whole computer that runs on marbles. My second marble machine was however much less based on logic - more on just making lots of cool noise.

But then I had an idea as to how the divide by two mechanisms from my first marble machine could be cascaded together to actually function as a sort of adder register, or counter. Once I had that idea, I knew I had to try it. And a few months later, I spent a couple of days in my workshop and built my binary marble adding machine.
